Description

Technical Field

[0001] The invention belongs to the field of medical technology, and in particular relates to a leg compression hemostasis braking device and a compression hemostasis method. Background Art

[0002] As the continuation of the external iliac artery, the femoral artery is the main puncture route for interventional diagnosis and treatment (such as coronary angiography, vascular interventional therapy) and hemodynamic monitoring of critically ill patients (such as arterial catheterization). Its large diameter and superficial anatomical position make it easy to operate, but at the same time, due to the high arterial pressure and loose surrounding tissue, improper hemostasis after puncture can easily lead to complications such as hematoma and pseudoaneurysm.

[0003] After femoral artery puncture, pressure needs to be applied to the puncture point to achieve hemostasis and closure of the arterial puncture point. Compression hemostasis devices are often used for hemostasis, such as the hemostasis devices disclosed in CN202010332175.8, CN202310296457.0, and CN202310296457.0. After femoral artery puncture, absolute bed rest is required for 24 hours. Depending on individual differences, the operated limb needs to be continuously straightened and braked for 6-12 hours, and hip flexion is prohibited. Although the aforementioned hemostasis device can perform compression hemostasis, it cannot limit the movement of the patient's legs and needs to be used in conjunction with a brake, such as a knee joint and ankle joint brake disclosed in CN202321368783.X. However, the separate settings of the hemostatic device and the brake are not compatible and inconvenient to operate, and the device has poor integrity, is relatively scattered, and is not easy to store and manage. In addition, the aforementioned hemostatic device has a good effect of compressing and stopping bleeding at the puncture point of femoral artery puncture, but has limited hemostatic effect on other bleeding situations, and is highly specialized and has poor versatility. Summary of the invention

[0004] In order to solve the technical problems existing in the prior art, the first aspect of the present invention is to provide a leg compression hemostasis brake device, which effectively prevents the patient's legs from bending by setting a fixed support plate, an upper fixing belt, a lower fixing belt and a knee joint fixing belt, and achieves the purpose of compression hemostasis through a compression hemostasis unit, and simultaneously plays the role of hemostasis and braking through a set of devices. In the second aspect, based on the same inventive concept, the present invention also provides a compression hemostasis method based on the aforementioned leg compression hemostasis brake device.

[0005] In an embodiment of the present invention, a leg compression hemostasis brake device includes a fixed support plate extending along the length direction of the leg, the upper end of the fixed support plate is fixed to the patient's waist and abdomen through an upper fixing belt, and the lower end of the fixed support plate is fixed to the patient's calf or the part below the calf through a lower fixing belt. The fixed support plate is provided with a plurality of through holes, through which a compression hemostasis unit for compressing and stopping bleeding at the leg and a knee joint fixing belt that surrounds the knee joint to prevent the knee joint from bending can be set.

[0006] The leg compression hemostasis method of the embodiment of the present invention is implemented based on the above-mentioned leg compression hemostasis braking device, and includes the following steps:

[0007] Compared with the prior art, the technical effects achieved by the preferred technical solution of the present invention include:

[0008] 1. The upper fixing belt is used to fix the patient's leg and rotate around the waist and abdomen for initial position fixation; the compression hemostasis unit is used to compress the bleeding position and stop bleeding; the knee joint fixing belt is used to fix the soft device around the knee joint for fixing the knee joint, which can effectively prevent the patient's leg from bending, increase the patient's comfort, and reduce the care burden of the patient's family; the lower fixing belt is used to fix the patient's foot to prevent the knee from bending for secondary reinforcement. Under the connection of the fixed support plate, the present invention realizes the two functions of hemostasis and braking through a set of devices at the same time, which is easy to operate, has strong integrity, and is easy to store and manage.

[0009] 2. The compression hemostasis unit of the present invention performs compression hemostasis by providing multiple airbags and providing a number of serrated clips between the airbags. During hemostasis, the airbags and the serrated clips compress the bleeding site together to stop bleeding. The serrated clips are provided between the two airbags to increase the friction and stability between the airbags, which can provide a stronger hemostasis effect. Especially in cases where a greater compression force or more stable hemostasis is required, this design can help keep the airbags better fixed to the target site and prevent the airbags from shifting, thereby improving the hemostasis effect. The compression hemostasis unit of the present invention can be used not only for hemostasis at the femoral artery puncture point, but also for compression hemostasis of other bleeding in the leg, and is more versatile and practical.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0015] Embodiment 1

[0016] This embodiment provides a leg compression hemostasis brake device, such as Figure 1 As shown, in a preferred embodiment, the hemostatic braking device includes a fixed support plate 1 extending along the length direction of the leg, the upper end of the fixed support plate 1 is fixed to the patient's waist and abdomen through an upper fixing belt 2, and the lower end of the fixed support plate 1 is fixed to the patient's calf or the part below the calf through a lower fixing belt 3, for example, the lower fixing belt 3 is fixed to the patient's ankle. The upper fixing belt 2 and the lower fixing belt 3 are strip-shaped flexible belts, which are fixed by connecting buttons and buttonholes.

[0017] The fixed support plate 1 has a plurality of through holes distributed in the height direction, through which a compression hemostasis unit 4 for compressing and stopping bleeding at the arterial puncture point and a knee joint fixing belt 5 surrounding the knee joint to prevent the knee joint from bending can be arranged, and the upper fixing belt 2 and the lower fixing belt 3 can also be fixed to the fixed support plate 1 through the through holes. The compression hemostasis unit 4 includes a hemostasis fixing belt 41 that can surround the thigh root and a compressor 42 installed on the hemostasis fixing belt 41 and pressurized directly above the puncture point. The compressor 42 can adopt a rotary compression hemostasis device in the prior art (such as disclosed in CN202411252161.X, CN202022080513.1, CN201510242822.5, or CN202420918788.3), compressing the puncture point after femoral artery puncture angiography or embolization to prevent bleeding at the puncture point, and the compression strength can be intelligently adjusted according to the specific situation of the patient.

[0018] The present invention uses an upper fixing belt 2 at the waist position to fix it around the waist and abdomen for an initial position fixation; a hemostatic fixing belt 41 is used to surround the bleeding position of the leg for a circle, and the position is adjusted so that the compressor 42 is pressed directly above the bleeding position (during femoral artery puncture, the hemostatic fixing belt 41 is used to surround the thigh root for a circle, and the compressor 42 is pressed directly above the puncture point), and the compression force is adjusted as needed to achieve the purpose of compression and hemostasis; a knee joint fixing belt 5 is used to fix a medium-soft device that surrounds the knee joint for a circle at the knee joint position, which is used to fix the knee joint with appropriate tightness, with the dorsalis pedis artery being able to be felt and the skin temperature being normal. The knee joint fixing belt 5 can effectively prevent the patient's leg from bending, increase the patient's comfort, and reduce the care burden of the patient's family; a lower fixing belt 3 is used to fix the ankle below the calf and surround the ankle for a circle to fix the patient's foot to prevent the leg from bending at the knee for secondary reinforcement.

[0019] Except for the plastic screw compression head of the compressor 42, the rest of the device can be disinfected and reused repeatedly to reduce the economic burden of patients and facilitate the widespread promotion of product use; at the same time, the upper fixing belt 2, the lower fixing belt 3, the hemostatic fixing belt 41 and the knee joint fixing belt 5 all adopt tough belts to improve the comfort of patients.

[0020] In one embodiment, the hemostatic fixation belt 41 is a strip-shaped tough belt, and the two ends of the hemostatic fixation belt 41 are connected by multiple buttons 6. Specifically, a plurality of first buttonholes distributed along the circumference and length directions of the leg can be set at one end of the hemostatic fixation belt 41, and the first buttonholes are located on the fixed support plate 1. A plurality of buttons are set at the other end of the hemostatic fixation belt 41, and the buttons on the hemostatic fixation belt 41 can be connected to the first buttonholes at different positions.

[0021] In one embodiment, the knee joint fixation belt 5 is a strip-shaped flexible belt, and the two ends of the knee joint fixation belt 5 are connected by multiple buttons 6. Specifically, a plurality of second buttonholes distributed along the circumference and length directions of the leg can be set at one end of the knee joint fixation belt 5, and the second buttonholes are located on the fixed support plate 1. A plurality of buttons are set at the other end of the knee joint fixation belt 5, and the buttons on the knee joint fixation belt 5 can be connected to the second buttonholes at different positions.

[0022] According to the different leg thicknesses of different people, select the first buttonhole / second buttonhole at a suitable circumferential position, and enter the first buttonhole / second buttonhole at different circumferential positions through the button to adjust the tightness of the hemostatic fixation belt 41 / knee joint fixation belt 5; according to the different leg lengths of different people, select the first buttonhole / second buttonhole at a suitable length position, and enter the first buttonhole at different length positions through the button to achieve comfortable fixation of the hemostatic fixation belt 41 / knee joint fixation belt 5.

[0023] In another preferred embodiment, for fixation at the knee joint, the triangular fixation principle is adopted according to the structure of the human knee joint. The knee joint fixation belt 5 on the knee joint socket is relatively wide, and the knee joint fixation belt 5 is evenly divided into two forks at the root of the kneecap on the inner side. The two forks avoid the knee joint and pass through the upper and lower sides of the knee joint respectively, and reach different parts of the second buttonhole and are fixed by buttons.

[0024] Embodiment 2

[0025] This embodiment provides a leg compression hemostasis braking device, the structure and principle of which are basically the same as those of the first embodiment, except that the structure of the compression hemostasis unit 4 is different.

[0026] Specifically, Figure 2As shown, in the present embodiment, the compression hemostasis unit 4 includes a hemostatic fixation belt 41 which can be wrapped around the leg and fixed (the structure of the hemostatic fixation belt is the same as that of the first embodiment and is not described in detail here), and a plurality of air bags 43 which are fixed on the inner side of the hemostatic fixation belt 41 and are distributed along the length direction of the leg and arranged side by side. The plurality of air bags 43 can work independently and are respectively connected to the inflation and deflation devices (not shown in the figure) through tracheas. The plurality of tracheas are arranged side by side and are provided with air valves for controlling the flow of gas therein, so that each air bag 43 can be independently inflated and deflated. Each airbag 43 extends along the circumference of the leg and can surround the leg in one circle or more than half a circle. A number of serrated clips 44 are arranged between adjacent airbags 43 and distributed along the circumference of the leg. The serrated clips 44 are made of silicone or rubber with a certain hardness. The serrated clips 44 can extend out to contact the skin or retract into the space between the airbags 43. By pushing the operating rod 45 inward, the corresponding serrated clip 44 can extend from between the two airbags 43 to the inside of the airbag 43 to contact the skin and be clamped and fixed by the two inflated airbags 43. Specifically, an operating rod 45 located on the outside of the hemostatic fixing band 41 can be connected to each serrated clip 44. The operating rod 45 is connected to the hemostatic fixing band 41 through a flexible connecting cover to limit the operating rod 45 from being separated from the hemostatic fixing band 41. The connection method between the operating rod 45 and the hemostatic fixing band 41 is the same as the connection method between the gear lever of an automobile and the body of the automobile. It is a prior art and will not be described in detail here.

[0027] When in use, the compression hemostasis unit 4 is fixed on the leg by a hemostasis fixing band. According to the bleeding position, the operating rod 45 in the area where the bleeding position is located is pushed inward to extend the corresponding serrated clip 44. The airbag 43 and the serrated clip 44 are pressed directly above the bleeding position. The airbag 43 in the area where the bleeding position is located is inflated by the inflation and deflation device to provide compression force to perform compression hemostasis. The magnitude of the compression force is adjusted by changing the inflation amount of the airbag 43 to change the air pressure in the airbag 43. The serrated clip 44 is arranged between the two airbags 43 to increase the friction and stability between the airbags 43, which can provide a stronger hemostasis effect. Especially in the case where a larger compression force or more stable hemostasis is required, this design can help keep the airbag 43 better fixed to the target site and prevent the airbag 43 from shifting, thereby improving the hemostasis effect.

[0028] It should be noted that when the femoral artery is punctured and hemostasis is stopped, in addition to compressing the hemostasis unit 4 to stop bleeding, the patient's leg needs to be braked by the fixed support plate 1, the upper fixing belt 2, the lower fixing belt 3 and the knee joint fixing belt 5. Bleeding from other wounds on the leg can be braked or not according to the doctor's advice.

[0029] Embodiment 3

[0030] This embodiment provides a leg compression hemostasis method, which is implemented based on the leg compression hemostasis brake device of embodiment 2. The leg compression hemostasis method includes the following steps:

[0031] Determine the pressure of the air bag and the serrated card to obtain the best hemostatic effect.

[0032]

[0033] Among them, F 总 is the total pressure applied by the compression hemostasis unit, i is the number of the airbags applying pressure, N is the number of airbags applying pressure, P 气 (i) is the pressure of the ith airbag (which can be obtained by setting up an air pressure sensor connected to the airbag), A 气 (i) is the area of ​​the compression surface of the i-th airbag, j is the serial number of the serrated card on the bleeding surface, M is the total number of serrated cards applying pressure on the bleeding surface, P 卡 (j) is the pressure of the jth sawtooth card (which can be obtained by embedding a pressure sensor on the sawtooth card), A 卡 (j) is the area of ​​the compression surface of the jth serrated card, η is the hemostatic effect, e is a natural constant, and θ is an adjustment parameter.

[0034] For different types of wounds, the optimal pressure for hemostasis is determined by the experience or experiments of medical staff. 总 is the actual force applied by the hemostasis unit 4, and the pressure of the airbag 43 and the pressure of the sawtooth card 44 can be adjusted by adjusting the inflation amount of the airbag 43 to adjust the total applied pressure F 总 Keep it close to the optimal pressure to avoid F 总 If the size is too small, the bleeding may not stop; or if the size is too large, necrosis may occur.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
